Pick your ZIP to see which of the two Reno locations is closer and what the area's households and vehicles look like. 4.7 stars from 550 Google reviews of the two Reno Xpress Oil & Lube Centers The Nevada DMV draws the Washoe testing area around Reno, Sparks, Washoe Valley, most of the area west of Washoe Valley, and the part of the county south of the 40th parallel, about midway through Pyramid Lake. That covers the ZIP codes most Washoe drivers live in. ## What each ZIP page shows Each of the 18 pages names the neighborhoods inside the ZIP, the closer location and the roads to it, the drive time to both locations, and the ZIP's figures from the Census Bureau's ACS 2020-2024 survey: people, households, vehicles per household and the mean commute. A household with two or three vehicles has two or three smog checks a year, so those numbers are a fair guide to how often the trip comes up. ## The two Reno locations Reno Northwest is at 6100 Mae Anne Ave, (775) 787-1000, open Monday to Friday 8 am to 5 pm and Saturday 8 am to 4 pm. Reno South is at 4993 Longley Ln near the airport and I-580, (775) 828-6996, open Monday to Friday 8 am to 5 pm and Saturday 8 am to 3 pm. Both are inside an Xpress Oil & Lube Center, both take drive-ins with no appointment, and both send results to the DMV electronically. Drive times come from OpenStreetMap routing in light traffic, so treat them as a guide. ## Outside the testing area The DMV exempts vehicles based in Incline Village, Crystal Bay, Sutcliffe, Nixon and Wadsworth, and in the rest of Nevada outside the urban parts of Washoe and Clark counties. Your renewal notice says Smog Check Required when a test is due. ## Closer to Reno Northwest [ZIP 89523 Northwest Reno Learn more](https://xpresssmogcenter.com/zip/89523/)[ZIP 89503 Old Northwest Reno and Rancho San Rafael Learn more](https://xpresssmogcenter.com/zip/89503/)[ZIP 89512 University and North Reno Learn more](https://xpresssmogcenter.com/zip/89512/)[ZIP 89439 Verdi Learn more](https://xpresssmogcenter.com/zip/89439/) ## Closer to Reno South [ZIP 89506 Stead and the North Valleys Learn more](https://xpresssmogcenter.com/zip/89506/)[ZIP 89508 North Valleys and Cold Springs Learn more](https://xpresssmogcenter.com/zip/89508/)[ZIP 89433 Sun Valley Learn more](https://xpresssmogcenter.com/zip/89433/)[ZIP 89519 Caughlin Ranch and Southwest Reno Learn more](https://xpresssmogcenter.com/zip/89519/)[ZIP 89509 Old Southwest Reno Learn more](https://xpresssmogcenter.com/zip/89509/)[ZIP 89501 Midtown and Downtown Reno Learn more](https://xpresssmogcenter.com/zip/89501/)[ZIP 89502 Southeast Reno and the airport Learn more](https://xpresssmogcenter.com/zip/89502/)[ZIP 89511 South Reno Learn more](https://xpresssmogcenter.com/zip/89511/)[ZIP 89521 Damonte Ranch and South Meadows Learn more](https://xpresssmogcenter.com/zip/89521/)[ZIP 89431 Sparks Learn more](https://xpresssmogcenter.com/zip/89431/)[ZIP 89434 East Sparks and Vista Learn more](https://xpresssmogcenter.com/zip/89434/)[ZIP 89436 Spanish Springs and Wingfield Springs Learn more](https://xpresssmogcenter.com/zip/89436/)[ZIP 89441 North Spanish Springs Learn more](https://xpresssmogcenter.com/zip/89441/)[ZIP 89704 Washoe Valley Learn more](https://xpresssmogcenter.com/zip/89704/) Every ZIP code listed is inside the Washoe County testing area (Nevada DMV, dmv.nv.gov/emission.htm, read 10/19/26).
